19C WRANGLER JT 4.5IN ADVENTURE X NO LIMITS COIL OVER SYS W/ FAST CD ADJUSTER

The Rock Krawler Suspension JT 4.5 inch ADVENTURE - X Mid-Arm System - DIESEL SPECIFIC is designed for Rubicon owners seeking a complete, bolt-in system with excellent articulation. It features 8 adjustable control arms with 100% Service Free Adventure Series joints, providing 70 degrees of misalignment to reduce factory control arm bind. The system allows for precision tuning of caster and pinion angles. It includes TRIPLE RATE front coils and QUAD RATE rear coils for on-road comfort, which is claimed to be better than OEM springs. The coils maintain proper "Free-length" for off-road articulation and remain seated in the coil bucket (with proper length shock). The kit includes correction pads to reduce spring bow and front and rear track bar geometry corrections for centered axles and improved on-road handling. The system is upgradable to an RK Longarm System.
